Data sheet transistor 2n2222

The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds.

Which transistor is equivalent of 2N2222?

2N2222 Equivalents 2N3904, BC547, BC548, and 2N3906 are 2N2222 comparable transistors.

Are 2N2222 and 2N2222A same?

The 2N2222A is the "improved" version of the 2N2222. You should be able to substitute the former for the latter in any circuit (but not necessarily vice versa). I would suspect that you wouldn't be able to find a supplier of the 2N2222 these days since the A version has been around for a long time.

Can I use BC547 instead of 2N2222?

The BC547 and 2N2222 transistors are both bipolar NPN transistors. The 2N2222 and BC547 transistors are both general-purpose transistors that are frequently used in electrical circuits; the BC547 transistor is one of the best transistor equivalents for the 2N2222 transistor.

How much voltage can a 2N2222 handle?

Both the 2N3904 and 2N2222 are identical in terms of handling collector-to-emitter voltages, and both can handle voltages of up to 40V. In simple terms, this effectively means that 40V is the maximum amount of voltage that the transistor can handle minus the voltage drop across the load connected to the collector.

How much current can a 2N2222 handle?

Typically, a 2N2222 transistor is able to switch 800 mA of load current through it, which may be considered quite high compared to the miniature size owned by these devices. High current switching capability also makes this device ideally suited for linear amplifier applications.

How fast can a 2N2222 switch?

The 2N2222 has a combined rise-time, fall-time, and storage-time of 310ns, thus the maximum switching frequency is about 3MHz so it's not appropriate for this application.

Where is 2N2222A transistor used?

2N2222 Applications As compared to the normal NPN BC547 transistor, the 2N2222 is extremely similar, but 2N2222 allows 800mA of collector current & also 652mW of power dissipation which can be utilized for driving larger loads as compared toBC547. It is typically used in automation & embedded projects.

How can use 2N2222 transistor as a switch?

As i switch the transistor basically allows a large current to flow through the collector marked in

Can I use C945 instead of 2N2222?

As far as specs are concerned the C945 has more gain, Hfe, than the 2N2222, but for most applications yes you could use C945 in place of the 2N2222. One issue though is C945 has different pin out than the 2N2222. The 2N2222 base has pin out of emitter-base-collector (base is center pin).

Can I use BC548 instead of 2N2222?

They are the same and are used interchangeably most of the time. 2N2222 is a metallic package TO-18 and PN2222 is a plastic package TO-92, you can refer to the datasheet of them. Can I use BC548 instead of BC547? NO, BC547 is an NPN and BC548 is a PNP transistor both the transistors are not substituted for each other.

Can I use 2N3904 instead of 2N2222?

The 2N3904 or 2N2222 will suffice if you require less than 200mA. The 2N2222 is the one to choose if you require more than 200mA but not more than 1A. For most circuits, a 2N3904 would suffice, however, if you need more above 200mA, a 2N2222 should be used instead.

Which transistor is best for switching?

Both PNP and NPN transistors can be utilized as switches. A basic terminal transistor can be handled differently from a signal amplifier by biasing both NPN and PNP bipolar transistors by an “ON / OFF” static switch. One of the main uses of the transistor to transform a DC signal “On” or “OFF” is solid-state switches.

Why is BC547 used?

BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it.

Can you use a transistor without a resistor?

A transistor without a resistor on the base is like an LED with no current-limiting resistor. Recall that, in a way, a transistor is just a pair of interconnected diodes. We're forward-biasing the base-emitter diode to turn the load on. The diode only needs 0.6V to turn on, more voltage than that means more current.

What is the cost of 2N2222 transistor?

₹55.00 FREE Delivery.

Can a transistor handle 12 volts?

If you're using 12V, you shouldn't have a problem with this. NPN (and PNP) transistors look like a diode from the base to the emitter. If you try to drive it without someway to limit the current, the transistor will be destroyed.

What is the smallest transistor ever made?

Now, by using atomically thin materials, scientists in China have created a transistor with a record-breaking gate length of just roughly one-third of a nanometer wide, only as thick as a single layer of carbon atoms, shedding light on how much smaller—if at all—transistors can possibly get.

What is the most powerful transistor?

As of 2022, the highest transistor count GPU is Nvidia's H100, built on TSMC's N4 process and totalling 80 billion MOSFETs.

What is the difference between PN2222 and 2N2222?

PN2222 vs 2N2222 For most purposes, they are interchangeable. But there are subtle differences between them. Firstly, package, PN2222 is in a molded-epoxy TO-92; 2N2222 is in a TO-18 metal can. Secondly, gain and leakage characteristics, PN2222A is properly a repackaging of 2N2222A, a better version of 2N2222.
